Recent forecast models for Karachi indicate a minimum temperature near 25°C on October 17, consistent with the city's typical October nocturnal range of 23–26°C under moderating post-monsoon conditions. Trader sentiment remains balanced between the 19°C-or-below and 29°C-or-higher outcomes because of uncertainty in sea-breeze strength and the lingering influence of an upper-level high-pressure system that has suppressed winds and sustained daytime heat into mid-month. Weakened onshore flow from the Arabian Sea could allow greater radiational cooling overnight, while persistent subsidence or reduced humidity might limit the diurnal drop. Pakistan Meteorological Department updates and refined model runs over the next 48 hours will likely resolve the key variables of wind direction and cloud cover that determine whether the low stays near seasonal norms or shifts toward either tail.
